Carry has taught Keenan how to control his scent and keep himself hidden and they have decided to stop using the psychic connection between them to play—very aware they are playing with fire as well as ice—and most definitely stop hooking up.
For once, things are okay between them, so of course the world decides to intrude and enforce the natural standards neither of them are able to live up to. 
This is episode 4 of “Cracking Ice”, a serialized novel that will be published every two weeks for the rest of the year.  Please start on episode 1.
